CAR-AXLE BGX.

' SPECIFICATION forming part of Letters Patent No. 288,780, dated November 20, 188,3.

i Application tiled September 1, 1593. (No model.) v

To all whom it nea/y concern/ K Be it known that I, WILLIAM Don, a citizen of the United States, residing at New York, in the county and State of New York, have invented new and useful Improvements in Car- Axle Boxes, of which the following is a speciiication. A

- My invention rel ates to the construction and arrangement of the dust-shield of car-axle boxes and to the construction and arrangement of the axle check-plate thereof, the whole being hereinafter fully described, and illustrated in the accompanying drawings, in which- Figure l shows my box in position on the runninggear of a car. Fig. 2 isa vertical longitudinal section ofthe box detached. Figs. 3, 4, and 5 areV detail views of the dust-shield. Fig. 6 is a vertical cross-section on the line .t fr, Fig. 2. Fig. 7 is a. horizontal section on the line y y, Fig. 2.

Similar letters indicate corresponding parts. The letter'A designates the body of a caraxle box, having the usual opening, B, in the rear wall thereof for the introduction of the car-axle, and C indicates a shield, serving to exclude dust and other impurities from the box through such opening. This dustshield is made of asbestus, it being molded or other wise brought to the required shape, and by this construction the shield is rendered incombustible, so that it is not liable to take re, as from a hot journal, while it is sudiciently soft or pliable to hug the journal, and thus form a tight joint therewith. Said shield C is provided with an opening, D, to receive the caraxle, and it is held in position on the axle by a supporting-frame, E, which is provided with a recess, F, to receive` the shield, so that the shield is left independent ofthe frame, and can be renewed, whendesirable, with facility.

The vertical edges of the supporting-frame E are fitted into grooves Gr Gr in the rear wall of the axle-box, so that it is removable, and the recess F is in the side of the frame facing the rear wall of the box, so that when the frame is put in place the shield is presented to such side of the box and is held in the recess by that means. A supplemental frame, H, is tted into the recess F ofthe supporting-frame, exterior of the shield, to act as a washer for the shield. For attaching the supporting-frame' E tothe box it is provided with a lip, I, through which a bolt, J, is driven in the body of the box.

The dust-shield C is divided at a point opposite to its opening D into au upper and lower section, C G2, which are fitted together by means of inclined mortises and tenons N O, so

that such opening is adjustable and accommo-A dates itself to axles of different diameters, the 6o size ofthe opening increasing'or diminishing with the withdrawal or approach of the sections from and toward each other. In the example shown the sections N O of the shield are two in number; but, if desired, each section may be subdivided in two or more parts.

In the top and bottom of the recess F of the supporting-frame are arranged springs P l?, which act on the sections C C2 of the shield with, a tendency to hold thesectonsin contact 7o with the axle.

In thefront wall of the axle-box is the usual opening, provided with a lid, Q, which may, if desired, be provided with spring-hinges for keeping it shut, and adjacent to such opening 7 5 within the box is located a vertical plate, R, known as a check-plate.7 it tending to cheek the longitudinal thrust of the car-axle. The vertical edges of the checkplate R are tted into grooves S S in the side walls ofthe axle- So box, so that it is removable, and on the lower edge of the plate is a ange, T, which projects outwardly and impinges against the front wall of the box at a point below its opening, so that this iiange tends to keep back the oil that otherwise might escape through the front wall opening.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a car-axle box, of 9o a frame, E, detachably connected with the inner end of the box, and constructed with the chamber F, and an outer wall provided with the opening D, shield C, composed of sections C' C2, arranged in the said chamber above and g5 IOO Q escaso 2. The combination, with a car-axle box having the opening B and vertical grooves G at the sides thereof, of the frame E, having thechamber F, lateral lip I, at its top, and an outer wall provided with the opening D, the side edges Aof the said frame being arranged in the vertical grooves and the lateral lip detachably bolted to the top ofthe box, the shield C, composed of sections C C, arranged above and below the axle, within the chamber of the frame, and the springs P I), arranged, respectively, between the upper and lower edges of the shield-sections and the top and bottom walls of the detachable frame, substantially as described.

3. The combination, with a car-axle box having the opening B in its rear wall, of the frame E, detachably secured to said rear wall, and having the chamber F, and an outer wall provided with the opening D, the asbestus shield C, composed of sections C G2. arranged above and below the axle, and the supplemental frame arranged within the detachable frame, between the shield and the rear wall of the box, said sections of the shield being capable of yiel ding independently of any movement of the supplemental frame, substantially as described.

4. The combination, with a car-axle box, of a dust-shield, O, composed of sections C C2, constructed, respectively, with inclined tenons N and inclined mortises O, iitting together, a frame, E, detachably connected with the rear wall of the axle-box, and having a chamber, F, in which the shield is arranged, and an outer wall provided with the opening D, and springs I), located within the chamber of the frame, between the top and bottom walls and the upper and lower edges of the shieldsections, substantially as described.

5. The combinatiomwith a car-axle box, of a frame, E, detachably connected with the rear wall of the box, and having a chamber, F, and an outer wall provided with the opening D, and a shield, C, arranged in said chamber and composed of upper and lower sections, C C2, constructed, respectively, with the 'inclined tenon N and inclined mortise O, tting together, substantially as described.

6. The combination, substantially as hereinbefore set forth, with a ca'r-axle box having an opening in the front wall thereof provided with a lid, ofthe axle check-plate having its lower edge provided with an outwardly-pro jecting iiange, which impinges against the front wall of the box at a point below its opening to prevent the escape of oil.

7. The combination, substantially as hereinbefore set forth, with a car-axle box having an opening in the front wall thereof provided with a lid, ofthe axle check-platehaving its vertical edges tted into grooves in the sidewalls of the box to render it removable, and having its lower edge provided with an outwardlyprojecting flange, which impinges against the front wall of the box ata point below its opening.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
